Body cavity drainage device and methods for using the same

Abstract

The present invention provides a drainage tube and method that removes fluid from a peritoneal, abdominal, or other body site. The tube has a central internal passageway for the flow of fluids. The tubing has one or more crossholes that extend through the tubing material and provide fluid communication between the passageway of the drain tube and the peritoneal, abdominal, or other body site of a subject.

1 . A lasso-shaped catheter comprising one or more crossholes. 
     
     
         2 . The catheter according to  claim 1 , wherein the catheter is configured to be placed in a body cavity. 
     
     
         3 . The catheter according to  claim 2 , wherein the body cavity is selected from the group consisting of: a peritoneal body site or abdominal body site. 
     
     
         4 . The catheter according to  claim 1 , wherein the catheter comprises 2 to 50 crossholes. 
     
     
         5 . The catheter according to  claim 1 , wherein the catheter is configured to provide for clog-free drainage of the body cavity. 
     
     
         6 . The catheter according to  claim 1 , wherein the catheter further comprises a therapeutic agent or therapeutic treatment. 
     
     
         7 . The catheter according to  claim 6 , wherein the therapeutic agent or therapeutic treatment is chemotherapy. 
     
     
         8 . The catheter according to  claim 1 , wherein the catheter is fluidically coupled to a drainage element. 
     
     
         9 . A system comprising:
 a lasso-shaped catheter comprising one or more crossholes; and   a pump.   
     
     
         10 . The system according to  claim 9 , wherein the system further comprises a heating element. 
     
     
         11 . The system according to  claim 9 , wherein the system further comprises a source of a chemotherapy. 
     
     
         12 . A method for draining fluid from a body cavity, the method comprising:
 positioning a lasso-shaped catheter one or more crossholes in the body cavity; and   draining fluid from the body cavity through the positioned catheter.   
     
     
         13 . The method according to  claim 12 , wherein the body cavity comprises a peritoneal or abdominal site. 
     
     
         14 . The method according to  claim 12 , wherein the fluid comprises a chemotherapy. 
     
     
         15 . (canceled)
